Abscisic acid inhibits PP2Cs via the PYR/PYL family of ABA-binding START proteins
ABA Receptor Rumbled? The plant hormone abscisic acid (ABA) is critical for normal development and for mediating plant responses to stressful environmental conditions.

As abscisic acid (ABA) receptors, PYR1/PYL/RCAR (PYLs) play important roles in ABA-mediated seed germination, but the regulation of PYLs in this process, especially at the transcriptional level, is still unclear.

Abscisic (ABA)-Aldehyde Is a Precursor to, and 1′,4′-trans-ABA-Diol a Catabolite of, ABA in Apple [PDF]
Previous (18)O labeling studies of abscisic acid (ABA) have shown that apple (Malus domestica Borkh. cv Granny Smith) fruits synthesize a majority of [(18)O]ABA with the label incorporated in the 1'-hydroxyl position and unlabeled in the carboxyl group (JAD Zeevaart, TG Heath, DA Gage [1989] Plant Physiol 91: 1594-1601).

News on ABA transport, protein degradation, and ABFs/WRKYs in ABA signaling [PDF]
The recent identification of abscisic acid (ABA) transporters provides an important insight into the delivery of ABA from the vascular system and its uptake by target cells. A putative connection with PYR/PYL receptors is envisaged, linking ABA uptake and intracellular perception by a fast and efficient mechanism.

A Partnership for ABA Responses [PDF]
The phytohormone abscisic acid (ABA) regulates a variety of processes in plants, including seed dormancy, seedling growth, and response to environmental stresses. A fascinating study by [Ni et al.

Effect of the minor ABA metabolite 7′-hydroxy-ABA on Arabidopsis ABA 8′-hydroxylase CYP707A3
To examine the effect of the minor abscisic acid (ABA) metabolite 7'-hydroxy-ABA on Arabidopsis ABA 8'-hydroxylase (CYP707A3), we developed a novel and facile, four-step synthesis of 7'-hydroxy-ABA from alpha-ionone. Structural analogues of 7'-hydroxy-ABA, 1'-deoxy-7'-hydroxy-ABA, and 7'-oxo-ABA were also synthesized to evaluate the role of the 7 ...

Reciprocal regulation of the TOR kinase and ABA receptor balances plant growth and stress response
SUMMARY As sessile organisms, plants must adapt to variations in the environment. Environmental stress triggers various responses, including growth inhibition, mediated by the plant hormone abscisic acid (ABA).

A Rice NAC Transcription Factor Promotes Leaf Senescence via ABA Biosynthesis1[OPEN]
The NAC transcription factor OsNAC2 plays an important role in ABA-dependent leaf senescence by targeting both abscisic acid biosynthetic and senescence-associated genes.
